With the help of her parents—David, 39, a computer consultant, and June, 38, a secretary at a special—needs school—and her brother Michael, 7, Krystal sawed oak boards into 2-in. blocks and pounded linoleum nails into the blocks to form the braille alphabet. (Three coats of acrylic keep them durable.) "They're just right for preschoolers and kindergartners," she says.
The folks at the Kansas City, Kans., school district thought so too. After her assignment was over (she got an A), Krystal donated the blocks to the district's vision-impaired program, where they were an immediate hit. "The little ones get so excited when they begin to spell words with the blocks," says program director Millie Justice. Krystal is now at work on new sets she plans to donate to any vision-impaired program that wants them—provided she can raise money for materials.
Her parents say they aren't surprised. When she was 5, Krystal wanted so badly to communicate with a deaf man at her church that, using a Sesame Street instructional book, she taught herself sign language. "Krystal has always been sensitive to people with disabilities," says June. "I've never seen a more compassionate teenager."
